A method and apparatus for evaluating the driving of a vehicle performing a journey on a road network is disclosed. The method comprises determining a fuel usage rate and an engine speed of a vehicle, and determining when the vehicle is coasting based upon at least one of the fuel usage rate and the engine speed of the vehicle. An acceleration of the vehicle, when the vehicle is determined to be coasting, is compared with a predetermined reference acceleration, and an application of braking during the coasting is determined based on the result of the comparison. A method and apparatus is also disclosed for determining a score indicative of the relative amount of time for which the vehicle is coasting without braking during a journey.

Apparatus and method for vehicle economy improvement

A method and apparatus is disclosed for evaluating the driving of a vehicle performing a journey on a road network, comprising determining at least one constant speed zone of the road network, a constant speed zone being a portion of the road network at which the vehicle can travel at a constant speed, said determination being based upon expected speeds of travel along the road network determined from positional data relating to the movements of a plurality of vehicles over time along the road network. A speed of the vehicle traversing the road network is determined at a plurality of times during the journey, and a value indicative of a consistency of the speed of the vehicle within the at least one constant speed zone is further determined.

A vehicle accelerometer system comprises an accelerometer for installation in a vehicle, a processor for selection of accelerometer output data items for inclusion in an accelerometer output data set representative of measurements by the accelerometer at a plurality of different vehicle locations, each accelerometer output data item being representative of a respective measurement by the accelerometer, and a storage device for storing the accelerometer output data set, wherein the processor is configured to process the accelerometer output data set to determine an orientation output representative of the orientation of the accelerometer with respect to the vehicle.
